The paper discusses three general classes of nonlinear programming models. Our objective is to show how to represent optimization problem, such as nonlinear programs, in a compact format using extended mathematical programming. This is a useful tool, especially in cases when complementarity...

Pollution charges are directly applied on exported and domestic, but not imported commodities. We investigate how environmental taxation affects foreign trade in the Czech Republic. Using computable general equilibrium modeling with bottom-up approach, we consider a small-open economy with...

We explore two methods of incorporating bottom-up abatement cost estimates into top-down modeling: economy-wide and sector-specific. Carbon emissions depend basically on technology and scale. Given the technology options, abatement is possible without a substantial reduction in scale. Otherwise...

Top-down models usually include piecewise-smooth functions to describe marginal cost curves, while bottom-up models describe those curves with a step function. When a bottom-up cost curve is available, we can explicitly represent this curve with a top-down model in order to replicate its shape...

Using choice experiment, this paper investigates how Belarusian citizens value planned Zvanets mire protection programmes. Two approaches are used to analyze ignored attributes: a debriefing question, and estimating parameters at the individual level. We have found inconsistencies between...

We look at perspectives of nature protection in a wetland of international importance in South-Western part of Belarus. The region is economically depressed, which may prove to be a factor in local conservation initiatives. A theoretical model is developed to identify conditions for the local...

The paper looks at people’s preferences for the changes in selected ecosystem services resulting from new management strategies of forest areas in Poland. It applies a generalized multinomial logit (G-MNL) model to interpret the results of a discrete choice experiment (DCE) study administered...

The returns to scientific collaboration have been widely acknowledged. The general trend observed in top scientific journals is an increase in collaborative activities both between researchers and between institutions, especially with regard to international co-authorship. Not only there is a...

We use a novel field experiment which jointly tests two implicit assumptions of updating models in a joint framework: that new information leads to new knowledge and that new knowledge can affect economic decisions. In the experiment, we elicit subjects’ prior knowledge state about a good’s...

Despite decades of anti-discriminatory legislation, wage discrimination against women is believed to be a major source of social inequality in the developed economies. In the present study we investigate the issue of gender wage gap in Poland. The analysis is carried out both with regard to the...
